PRINCETON, N.J.–(BUSINESS WIRE)–Bristol Myers Squibb (NYSE:BMY) today announced that the U.S. Food and Drug Administration (FDA) has accepted its supplemental New Drug Application (sNDA) for Zeposia® (ozanimod) for the treatment of adults with moderately to severely active ulcerative colitis (UC). Following the redemption of a Priority Review Voucher with the submission, the FDA assigned a Prescription Drug User Fee Act (PDUFA) goal date of May 30, 2021.
“People living with ulcerative colitis often struggle to manage their disease and can face a severe impact to their lives, highlighting a need for new oral treatment options with proven safety and efficacy profiles that can be utilized early in the treatment journey,” said Mary Beth Harler, M.D., head of Immunology and Fibrosis Development, Bristol Myers Squibb. “We look forward to continuing to work with the FDA to bring Zeposia to those living with this serious, chronic disease.”
The sNDA submitted to the FDA is based on results from True North, a pivotal, placebo-controlled Phase 3 trial evaluating Zeposia as an induction and maintenance therapy in adults with moderately to severely active UC. True North met both primary endpoints, demonstrating highly statistically significant and clinically meaningful results for clinical remission compared to placebo at induction at Week 10 and in maintenance at Week 52. The overall safety observed in True North was consistent with the known safety profile for Zeposia in approved labeling.
Bristol Myers Squibb thanks the patients and investigators who participated in the Zeposia Phase 3 UC True North clinical trial.
About True North
True North is a Phase 3, multicenter, randomized, double-blind, placebo-controlled trial comparing the efficacy and safety of Zeposia 1 mg in patients with moderately to severely active ulcerative colitis who did not adequately respond to prior treatment. In the induction phase, a total of 645 patients were randomized to receive Zeposia (n=429) or placebo (n=216) in Cohort 1, of whom 94% and 89%, respectively, completed the induction period. At study entry, mean age was 42 years, 60% were male and mean disease duration was 7 years; patient characteristics were well-balanced across treatment groups. Cohort 1 patients were randomized 2:1 to Zeposia or placebo and treated once daily for 10 weeks. Cohort 2 (n=367) was an open-label arm where patients were treated once daily with Zeposia for 10 weeks.
For the maintenance phase, patients on Zeposia from either Cohort 1 or 2 who achieved clinical response in the induction phase at Week 10 were re-randomized 1:1 to Zeposia (n=230) or placebo (n=227) through Week 52. Of these, 80% and 54.6% of patients who received Zeposia and placebo, respectively, completed the study. Patients discontinuing treatment due to treatment-emergent adverse events included 3 patients receiving Zeposia and 6 patients receiving placebo; disease relapse (13.5% Zeposia, 33.9% placebo) was the most common reason for discontinuation. Patients on placebo who achieved clinical response in the induction phase at Week 10 remained on placebo during this blinded maintenance phase.
In Cohort 1 of the induction phase and in the re-randomized patient group in the maintenance phase, approximately 30% of patients had prior TNF-inhibitor exposure.
All eligible patients were rolled into an open-label extension trial, which is ongoing and designed to assess the longer-term profile of Zeposia for the treatment of moderately to severely active ulcerative colitis.
The primary endpoints in True North are the proportion of patients in clinical remission based on a composite clinical and endoscopic score (3-component Mayo Score) at Week 10 in the induction phase, and at Week 52 in the maintenance phase. Secondary endpoints include the proportion of patients achieving clinical response at Week 10 and Week 52, the proportion of patients with endoscopic improvement (endoscopy score ≤1) at Week 10 and Week 52, the proportion of patients with mucosal healing at Week 10 and Week 52, and clinical remission at Week 52 in patients that were in remission at Week 10. In this study, mucosal healing is defined as endoscopic improvement with histologic remission. More information can be found on www.clinicaltrials.gov, NCT02435992.
About Ulcerative Colitis
Ulcerative colitis, a chronic inflammatory bowel disease (IBD), is characterized by an abnormal, prolonged immune response that creates long-lasting inflammation and ulcers (sores) in the mucosa (lining) of the large intestine (colon) or rectum. Symptoms include bloody stools, severe diarrhea and frequent abdominal pain. Ulcerative colitis has a major impact on patients’ health-related quality of life, including physical functioning, social and emotional well-being and ability to work. Many patients have an inadequate response or do not respond at all to currently available therapies. It is estimated that approximately 1.6 million people in the United States have IBD, which includes ulcerative colitis and Crohn’s disease.
About Zeposia® (ozanimod)
Zeposia® (ozanimod) is an oral, sphingosine-1-phosphate (S1P) receptor modulator that binds with high affinity to S1P receptors 1 and 5. Zeposia reduces the capacity of lymphocytes to exit from lymph nodes, reducing the number of circulating lymphocytes in peripheral blood. The mechanism by which Zeposia exerts therapeutic effects in ulcerative colitis is unknown but may involve the reduction of lymphocyte migration into the inflamed intestinal mucosa.
Bristol Myers Squibb is continuing to evaluate Zeposia in an open-label extension trial, which is ongoing and designed to assess the longer-term profile of Zeposia for the treatment of moderately to severely active ulcerative colitis. The company is also investigating Zeposia for the treatment of moderately to severely active Crohn’s disease in the ongoing Phase 3 YELLOWSTONE clinical trial program.
Zeposia was approved by the U.S. Food and Drug Administration (FDA) for the treatment of adults with relapsing forms of multiple sclerosis (RMS) in March 2020. The European Commission approved Zeposia for the treatment of adult patients with relapsing remitting multiple sclerosis (RRMS) with active disease as defined by clinical or imaging features in May 2020. The European Medicines Agency validated Bristol Myers Squibb’s Marketing Authorization Application for Zeposia for the treatment of adults with moderately to severely active ulcerative colitis in December 2020. Zeposia is not approved for the treatment of ulcerative colitis in any country.
U.S. FDA-APPROVED INDICATION FOR ZEPOSIA
ZEPOSIA is indicated for the treatment of relapsing forms of multiple sclerosis (MS), to include clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease, in adults.
IMPORTANT SAFETY INFORMATION
- Patients who in the last 6 months, experienced myocardial infarction, unstable angina, stroke, transient ischemic attack (TIA), decompensated heart failure requiring hospitalization, or Class III/IV heart failure or have a presence of Mobitz type II second or third-degree atrioventricular (AV) block, sick sinus syndrome, or sino-atrial, unless the patient has a functioning pacemaker
- Patients with severe untreated sleep apnea
- Patients taking a monoamine oxidase (MAO) inhibitor
Infections: ZEPOSIA may increase the susceptibility to infections. Life-threatening and rare fatal infections have occurred in patients receiving ZEPOSIA. Obtain a recent (i.e., within 6 months or after discontinuation of prior MS therapy) complete blood count (CBC) including lymphocyte count before initiation of ZEPOSIA. Delay initiation of ZEPOSIA in patients with an active infection until the infection is resolved. Consider interruption of treatment with ZEPOSIA if a patient develops a serious infection. Continue monitoring for infections up to 3 months after discontinuing ZEPOSIA
- Herpes zoster was reported as an adverse reaction in ZEPOSIA -treated patients. Herpes simplex encephalitis and varicella zoster meningitis have been reported with sphingosine 1-phosphate (S1P) receptor modulators. Patients without a healthcare professional-confirmed history of varicella (chickenpox), or without documentation of a full course of vaccination against varicella zoster virus (VZV), should be tested for antibodies to VZV before initiating ZEPOSIA. A full course of vaccination for antibody-negative patients with varicella vaccine is recommended prior to commencing treatment with ZEPOSIA
- Cases of fatal cryptococcal meningitis (CM) were reported in patients treated with another S1P receptor modulator. If CM is suspected, ZEPOSIA should be suspended until cryptococcal infection has been excluded. If CM is diagnosed, appropriate treatment should be initiated.
- Progressive Multifocal Leukoencephalopathy (PML) is an opportunistic viral infection of the brain that typically occurs in patients who are immunocompromised, and that usually leads to death or severe disability. No cases of PML were identified in active-controlled MS clinical trials with ZEPOSIA. PML has been reported in patients treated with S1P receptor modulators and other MS therapies and has been associated with some risk factors. If PML is suspected, withhold ZEPOSIA and perform an appropriate diagnostic evaluation. If confirmed, treatment with ZEPOSIA should be discontinued
- In clinical studies, patients who received ZEPOSIA were not to receive concomitant treatment with antineoplastic, non-corticosteroid immunosuppressive, or immune-modulating therapies used for treatment of MS. Concomitant use of ZEPOSIA with any of these therapies would be expected to increase the risk of immunosuppression. When switching to ZEPOSIA from immunosuppressive medications, consider the duration of their effects and their mode of action to avoid unintended additive immunosuppressive effects
- Use of live attenuated vaccines should be avoided during and for 3 months after treatment with ZEPOSIA. If live attenuated vaccine immunizations are required, administer at least 1 month prior to initiation of ZEPOSIA
Bradyarrhythmia and Atrioventricular Conduction Delays: Since initiation of ZEPOSIA may result in a transient decrease in heart rate and atrioventricular conduction delays, dose titration is recommended to help reduce cardiac effects. Initiation of ZEPOSIA without dose escalation may result in greater decreases in heart rate. If treatment with ZEPOSIA is considered, advice from a cardiologist should be sought for those individuals:
- with significant QT prolongation
- with arrhythmias requiring treatment with Class 1a or III anti-arrhythmic drugs
- with ischemic heart disease, heart failure, history of cardiac arrest or myocardial infarction, cerebrovascular disease, and uncontrolled hypertension
- with a history of Mobitz type II second-degree or higher AV block, sick-sinus syndrome, or sinoatrial heart block
Liver Injury: Elevations of aminotransferases may occur in patients receiving ZEPOSIA. Obtain liver function tests, if not recently available (i.e., within 6 months), before initiation of ZEPOSIA. Patients who develop symptoms suggestive of hepatic dysfunction should have hepatic enzymes checked and ZEPOSIA should be discontinued if significant liver injury is confirmed. Caution should be exercised when using ZEPOSIA in patients with history of significant liver disease
Fetal Risk: There are no adequate and well-controlled studies in pregnant women. Based on animal studies, ZEPOSIA may cause fetal harm. Women of childbearing potential should use effective contraception to avoid pregnancy during treatment and for 3 months after stopping ZEPOSIA
Increased Blood Pressure: Increase in systolic pressure was observed after about 3 months of treatment and persisted throughout treatment. Blood pressure should be monitored during treatment and managed appropriately. Certain foods that may contain very high amounts of tyramine could cause severe hypertension in patients taking ZEPOSIA. Patients should be advised to avoid foods containing a very large amount of tyramine while taking ZEPOSIA
Respiratory Effects: ZEPOSIA may cause a decline in pulmonary function. Spirometric evaluation of respiratory function should be performed during therapy, if clinically indicated
Macular edema: S1P modulators have been associated with an increased risk of macular edema. Patients with a history of uveitis or diabetes mellitus are at increased risk. Patients with a history of these conditions should have an ophthalmic evaluation of the fundus, including the macula, prior to treatment initiation and regular follow-up examinations. An ophthalmic evaluation is recommended in all patients at any time if there is a change in vision. Continued use of ZEPOSIA in patients with macular edema has not been evaluated; potential benefits and risks for the individual patient should be considered if deciding whether ZEPOSIA should be discontinued
Posterior Reversible Encephalopathy Syndrome (PRES): Rare cases of PRES have been reported in patients receiving a S1P receptor modulator. If a ZEPOSIA-treated patient develops unexpected neurological or psychiatric symptoms or any symptom/sign suggestive of an increase in intracranial pressure, a complete physical and neurological examination should be conducted. Symptoms of PRES are usually reversible but may evolve into ischemic stroke or cerebral hemorrhage. Delay in diagnosis and treatment may lead to permanent neurological sequelae. If PRES is suspected, treatment with ZEPOSIA should be discontinued
Unintended Additive Immunosuppressive Effects from Prior Immunosuppressive or Immune-Modulating Drugs: When switching from drugs with prolonged immune effects, the half-life and mode of action of these drugs must be considered to avoid unintended additive immunosuppressive effects while at the same time minimizing risk of disease reactivation. Initiating treatment with ZEPOSIA after treatment with alemtuzumab is not recommended
Severe Increase in Disability After Stopping ZEPOSIA: Severe exacerbation of disease, including disease rebound, has been rarely reported after discontinuation of a S1P receptor modulator. The possibility of severe exacerbation of disease should be considered after stopping ZEPOSIA treatment so patients should be monitored upon discontinuation
Immune System Effects After Stopping ZEPOSIA: After discontinuing ZEPOSIA, the median time for lymphocyte counts to return to the normal range was 30 days with approximately 90% of patients in the normal range within 3 months. Use of immunosuppressants within this period may lead to an additive effect on the immune system, therefore caution should be applied when initiating other drugs 4 weeks after the last dose of ZEPOSIA
Most common Adverse Reactions (≥ 4%): upper respiratory infection, hepatic transaminase elevation, orthostatic hypotension, urinary tract infection, back pain, and hypertension.
